ROTARY FLUlD-lMPELLlNG DEV ICE,

To all whom it may concern:

Be it known that I, ALBERT E. GUY, of

' Trenton, Mercer county, New Jersey, have invented a new and useful Improvement in Rota Fluul impelling Devices, of which the 0 lowing IS a specification.

- High-speed rotary fiuid-impelling devices,

. 'be brought to higher initial pressure, tiis difficulty is overcome.

I accomplish this by combining with the 'impelling device an inector disposed on the suction side thereof and acting upon the incoming liquid to 111-.

crease its pressure, the said injector being ac a section of a centrifugal pum em ,my invention on the linea: :eof iig. 2. 1g. 2

pipe and l2. These branch pipes lead from.- an

tuated by a portion of the flow delivere by the im llin device. In this way I make it possib e to rive a centrifu al pump at high speed by a-steam-turbine, or example, and thus obtain a delive at' high. pressure, which, for purposes of oiler-feedand other special uses, is often very desirable;

My invention consists in the method of in creasing the initial pressure of the incoming flow and an apparatus wherein said metho is embodied, as moreparticularly pointed out in the claims. dr

In the accompanying awin 's Fi ure 1 have;

Similar numbers of reference indicate like parts. 1 is the impeller-wheel. The shaft ,2,on j

which said w eel is carried, is journaled 1n the-walls of thecasing 3 and is actuated by a any suitable motor, represented at 4.- The impeller-wheel is here,duplex and has two',

sets of blades 5 6, so that when said wheel is rotated, the liquid is drawn'in at both ends of the wheel and delivered at its mid dlc portion,

as shown by the arrows. The pu m p-casi n g 3 has an annular chamber 7 surrounding the wheel and connnumcatmg with delivery- 5, and also two side rhambers 9 10,

annular chamber 13, which surrounds the gnozzle end 1 4 of'the suction-pipe 15. Said chamber 13 connects by pipes 17 18 with the. delivery-pipe 8.

The nozzle 'end 14 of suetion-pipe-15, with l the annular chamber-13, forms an injector invwhichthe kinetic energy of a portion of the [outgoing liguid is imparted to the incomin r i liquid-that is to say, the portion of liquir 2 How which passes from the delivery-pipe- 8 through the pipes 17 18 to the annular cham f ber 1 3 and which escapes from said annular chamber through the constricted space sur- 'rounding. the nozzle end 14 or the suction--, pipe imparts its kineticenergv: to the flow passing through said nozzle, and jthus increases the pressure of the liquid which proceeds to theimpeller-wheel.
